| Use advice for data set | Users of this data should consider the precision of the input-output data stemming from the company's public environmental impact assessment when applying this information to their LCA models. Ensure the functional unit of 1 ton of propylene product aligns with the system boundaries of your model, and attention should be given to the exclusion of end-of-life treatment, infrastructure construction, and equipment maintenance phases from the scope of the assessment. Furthermore, the environmental load should be allocated between propylene and by-products using the mass distribution method, acknowledging waste discharges from the process. |
| Technical purpose of product or process | The propylene produced through the catalytic cracking process at Sinopec Zhanjiang Dongxing Petrochemical Co., Ltd. is intended for use in various chemical manufacturing applications. It serves as a fundamental building block in the production of polypropylene plastics, acrylonitrile, propylene oxide, and a myriad of other chemical intermediates and products. Given its production scale, the propylene is suitable for both small-scale specialty uses and large-scale industrial applications. |

| Mathematical model | |
| Model description | The consumption of raw materials, energy, electricity, steam, water and auxiliary chemicals involved in each sub-stage is considered, and the output considers propylene and by-products (such as C4 products produced by the propane dehydrogenation process. The mass distribution method is used to quantify the products The environmental load between propylene and by-products. In addition, this model also considers the waste discharge of each process. This study focuses on the environmental impact analysis of different propylene production processes. Therefore, the utilization of propylene hydrocarbons and the end-of-life treatment of their products, as well as infrastructure Construction and equipment maintenance are outside the scope of this assessment. |
